To all whom it may concern:

Be it known that 1, CHARLES W. Nantes, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sound-Reproducing Machines, of which the following is a specification.

My invention relates to improvements in sound reproducing machines of either the phonograph or graphophone type, and more particularly to that class of sound reproducingmachinesin which the sound reproducing and amplifying means are inclosed within a cabinet.

The primary object of the invention is to provide a generally improved sound reproducing machine of this class having unproved amplifying means wherebythe quality of the reproduction may be improved and regulated at the will of the operator and while the machine is in operation. lln carrying out this object I provide a plurality of graduated amplifiers or horns having their open ends arranged at one side of the cabinet and their neck portions movably supported and adapted to be brought into and out of communication with the common sound conduit of the sound reproducing means whereby one or more amplifiers may be brought into use and the volume or strength of the tone regulated as desired. 1 or example,-in the present embodiment of the invention the amplifiers or horns have their open ends superposed and are graduated from top to bottom for the production of a mild, medium or strong tone, respectively, or by bringing two of such amplifiers or horns in communication with the sound conduit a blended or intermediate tone will result.

A further object of the invention is to provide means wherehy the reproduced sound issuing from the amplifier may be modified, controlled and directed at the mouth or open end of the respective amplifier and as issuing from the open side of the cabinet.

lVith the above mentioned and other ends in view, the invention consists in the novel construction, arra'. gement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings -forming a part of this specification, Figure l, is a front elevation of the improved sound reproducmg machine of the cabinet type, a portion of the walls of the latter being broken away for the purpose of clearer illustration of the parts. Fig. 2, a similar view of the same, partly in section and partly in side elevation. Fig. 3, a rear view of the same, a portion or" the rear wall being broken away for the purpose of clearer illustration of the parts. Fig. 4, aside elevation of an amplitying horn provided in its mouth or open end with sound modifying and deflecting elements. Fig. 5, a front elevation of the same. Fig. 6, a view or the handle operating and adjusting mechanism used in connection with the sound modifying and defleeting elements shown in Figs. 4 and 5. Fig. 7, a top plan view of the mechanism for movably supporting and adjusting the neck portions of the amplifiers or horns with respect to the common sound conduit communicating with the sound reproducing means. Fig. 8, a rear view of the same, showing an adjustment whereby the sound waves from the common sound conduit communicate directly with the neck portion of the second or intermediate amplifier. Fig. 9, a similar view showing an adjustment in which the sound waves communicate with the neck portions of two of such amplifiers.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The present embodiment of the improved sound reproducing machine comprises a cabinet consisting of a main body portion 1, provided at its top with a supporting wall or plate 1 and a removable cover 2. The supporting wall or plate 1, divides the'main compartment of the cabinet from the supplemental or machine compartment above,

and, in, the present instance, supports the motor 3, through the medium of a depending bracket l, and the turn-table 5, adapted to receive the disk record and being driven through the medium of a spindle 6, provided with a pulley 6, communicating with a pulley '2', of the motor 3, through the medium of a cord or belting 7 The cabinet is provided at its with a vertically extending opening 8, and a plurality of graduated amplifiers or horns 9, having their open ends superposed within said cabinet and alon said opening, the enlarged or delivery ends of said amplifiers being preferably pivotally mounted, and

terminating at their rear in upwardly erltending neclr portions 9 adapted to be brought into or out of communication with the sound box arm 10, or of the sound reproducing mechanism as hereinatter described.

The sound box arm 10', in the present instance, extends rearwardly from the sound box 11, and stylus 12, and is swivelly or pivotally connected to a common conduit pipe 13, extending through the supporting plate 1".

As a means for movably supporting the neck portions 9* of the amplifiers 9, in proper relative position with respect to the common sound conduit 18, as well as providing means whereby said neck portions may,

be brought into and out oi registry with said conduit member 13, for varying or modifying the tone or amplification oi the sound waves, said neck portions 9, extend through and are carried by a supporting slide member 14, the latter being connected to suitable guide members 15, secured to-the rear walls of the cabinet immediately beneath the common conduit 13, the latter being preferably provided with wing members 13", adapted to extend above the ends of the neck portions 9 of the amplifiers when the latter are. not brought into communication with the common sound conduit 13.

The slide member 14;, is adapted to be operated through the medium of a handle 16, extending through the adjacent wall of the cabinet, said handle and the slide member 14:, and neck portions 9 being. adapted to be moved toand secured in certain predetermined positions through the medium of a spring actuated bolt 17, mounted in a bracket 18, and adapted to rest within notches 16?, of the handle.

The upper, middle, and lower amplifiers 9, are adapted, in, the present instance, to produce a mild, medium, and strong tone, respectively, and by reason of the construction just described, it will be observed that the horn or amplifier necks 9, may be shifted laterally whereby to bring one or the other into direct communication with the common conduit 18, as for example,the intermediate amplifier as shown in Figs. 3 and 8, or to direct the sound waves equally into two of such necks shown in Fig. 9, of the drawings w reby effect of the two amplifiers or horns will be obtained.

front or open or the amplifiers may be secured along the open or portion of the cabinet by means of pivot bolts 19, connected, in the present instance, to brackets some or said brackets being socured, in the present inst to transver e bars 8 the 7 god in it desired, the opening 8, able door {not shown ,1 is in use,

means for selectively moving the receiving nisaesv the cabinet may be divided into suitable compartments 21, through the medium of partitions 22, said compartments affording means torv storing the disk records 28, and being adapted to be opened and closed through the medium ,of suitable panel doors As a means for further modifying and deiiecting the sound waves, one or more amplitying horns may be provided at the mouth or delivery end with a plurality of sound modifying and deflecting elements 25, said elements being preferably pivotally mounted within the mouth or" the horn and connected at their free ends by means of connecting links 26. As a means for operating and adjusting said elements 25, a rock shaft 27, may be provided, said shaft being suitably connected to one or more of the members 25, and extending through one wall of the cabinet and terminating in an operating handle 2?. As a means for securing said deflecting members or elements25, in any position to which they may be adjusted, the shaft 27, may be provided with a spring pawl or member 28, adapted to seat itself in any of the notches or grooves 29 or" a disk plate 29, secured to the adjacent outer wall of the cabinet From the foregoing description, taken in connection with the accompanying draw ings, the'operation and advantages of my invention will be readily understood,
